The figure shows a ladder leaning against a wall forming a triangle What is the value of x in the figure A 66 degrees B

Answer :

D. 24 degrees
A triangle is 180 degrees in all.
A right angle is 90 degrees.
You subtract 66 from 180 and then 90 from your answer. What you are left with is x.
180-66= 144
144-90=24 degrees
I hope this helps!
